stm32l0xx: Fix warnings for extraneous parentheses

Building with clang reports the following warnings:

stm32l0xx_hal_rcc.c.c: error: equality comparison with extraneous
parentheses [-Werror,-Wparentheses-equality]
    if((sysclk_source == RCC_CFGR_SWS_MSI) )
        ~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~

Removing the extra () fixes the warning
