Correct syslog message in UT_BSP_Unlock

[jphickey]

Describe the bug
The log message in UT_BSP_Unlock has the wrong function name (OS_MutSemTake). Appears to be a copy/paste error from UT_BSP_Lock above.

To Reproduce
N/A (does not fail in normal operation)

Expected behavior
Log message should have OS_MutSemGive, not OS_MutSemTake
