    drm/xe/gt: Fix assert in L3 bank mask generation
    
    What needs to be asserted is that the pattern fits in the number
    of bits provided by the user in patternbits, otherwise it would
    be truncated when replicated according to the mask, which is
    likely not the intended use of this function.
    The pattern argument is a bitmap so use find_last_bit() instead
    of fls(). The bit position starts at index 0 so remove "or equal"
    from the comparison. XE_MAX_L3_BANK_MASK_BITS would be the
    returned value if the pattern is 0, which can be the case on some
    platforms.
    
    v2: Check the result does not overflow the array (Lucas De Marchi)
    
    v3: Use __fls() for long and handle mask == 0  (Lucas De Marchi)
