Overflow in bladeRF-cli number of samples

[Algafix]

Hello!

In bladeRF-cli, the n value in rx config (probably in tx too) overflows at 2**32:

rx config file=test.bin n=3G format=bin

  State: Running
  Channels: RX1
  Last error: None
  File: test.bin
  File format: SC8 Q7, Binary
  # Samples: 3221225472
----------------------------
rx config file=test.bin n=4G format=bin

  State: Running
  Channels: RX1
  Last error: None
  File: test.bin
  File format: SC8 Q7, Binary
  # Samples: infinite
----------------------------
rx config file=test.bin n=5G format=bin

  State: Running
  Channels: RX1
  Last error: None
  File: test.bin
  File format: SC8 Q7, Binary
  # Samples: 1073741824

In the code of rx.c:rx_cmd_config the variable n is declared as unsigned int. However, n_samples is declared as size_t which in my machine is long unsigned int.

Hence, changing the code form:

if (!strcasecmp("n", argv[i])) {
    /* Configure number of samples to receive */
    unsigned int n;
    bool ok;
    
    n = str2uint_suffix(val, 0, UINT_MAX, rxtx_kmg_suffixes,
                        (int)rxtx_kmg_suffixes_len, &ok);
    
    if (ok) {
        MUTEX_LOCK(&s->rx->param_lock);
        rx_params->n_samples = n;
        MUTEX_UNLOCK(&s->rx->param_lock);
} else {

to:

if (!strcasecmp("n", argv[i])) {
    /* Configure number of samples to receive */
    uint64_t n;
    bool ok;
    
    n = str2uint64_suffix(val, 0, UINT64_MAX, rxtx_kmg_suffixes,
                        (int)rxtx_kmg_suffixes_len, &ok);
    
    if (ok) {
        MUTEX_LOCK(&s->rx->param_lock);
        rx_params->n_samples = n;
        MUTEX_UNLOCK(&s->rx->param_lock);
}

Fixes it on my machine but not in one where size_t is just unsigned int.
