ext/hal: stm32f1xx: Fix warnings for extraneous parentheses

Building with clang reports the following warnings:

stm32f1xx_hal_tim.c: error: equality comparison with extraneous
parentheses [-Werror,-Wparentheses-equality]
  else if((htim->State == HAL_TIM_STATE_READY))
           ~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~

Removing the extra () fixes the warning

*Fix warnings for extraneous parentheses
Using clang 7.0.1, if ((htim->State == HAL_TIM_STATE_BUSY))
generates warnings. Remove the extra parentheses
