mon/OSDMonitor.cc : set erasure-code-profile to "" when create replic…

…ated pools.

when we create a pool specify a rule, for example "ceph osd pool create foo replicated 10 rule_foo",
we will set pool foo erasure-code-profile to rule_foo,
if there has an erasure-code-profile names rule_foo, use "ceph osd erasure-code-profile rule_foo" will fail,
"Error EBUSY: foo pool(s) are using the erasure code profile 'rule_foo'", this is wrong.

we should do:
1. set erasure-code-profile to "" when create replicated pools
2. whether erasure-code-profile is used by pool not only judge pool erasure_code_profile property and also the pool is_erasure
